The 2001 GMC C Series has 2 recalls, the more serious being a cracked internal component inside the second- and third-row outboard seatbelt retractors that can prevent the belt from locking in a crash, leaving rear occupants without proper restraint.
On vehicles equipped with an IMPCO liquefied petroleum gas conversion kit, engine backfire can cause a fuel inlet fitting to break free from the throttle body. If that happens, the vehicle loses its fuel supply and stalls, though the separated part stays retained rather than falling free.

What the fix does
